Installation of Stainless Steel Cladded PEEK Capillaries
• to the autosampler needle and
• to PEEK columns (like many bio-inert columns).
For the installation of bio-inert ZDV unions, see “Installation of the Bio-inert
Zero Dead Volume (ZDV) Union” on page 59.
First installation of a capillary to a soft connector
1 When tightening a fitting for the first time, start from the finger-tight
position (which does not necessarily need to be a vertical wrench position)
and rotate the wrench by 180 – 210 °. Staying below 180 ° (grey arrow) will
not be sufficiently tight, more than 210 ° (red arrow) could damage the
capillary.
Second and subsequent installations of a capillary to a soft connector
1 When tightening the fitting for the second and subsequent times, again start
from the finger-tight position (which is not necessarily a vertical wrench
position) and rotate the wrench by 135 – 180 °. Staying below 135 ° (grey
arrow) could be insufficiently tight enough, more than 180 ° (red arrow)
could damage the capillary.
